Slime are enemies that have appeared in A Link to the Past.
Slimes are enemies that will transform from certain enemies if Link uses the Quake Medallion near them or sprinkling Magic Powder over certain enemies. They are resembling an onion-like creature, and behave similar to the Zols and Gels. Slimes are considered as one of the weakest enemies in this game, and Link can kill them with one slash with his sword. Link can always use the Quake Medallion on strong enemies to transform them into Slimes so that he can defeat them easier.
